Hi Derek,

 

 

In your configuration, since the LTM's aren't the default gateway or the routing next hop for any of your devices (all connections must be using SNAT), then you are correct that floaters are not necessary.

 

 

Connection mirroring is done via the primary failover addresses defined in the high availability config, so there's no requirement there for floaters either.

 

 

I haven't checked the iControl SDK, but I would imagine one of the items you can check would be the defined peer address for each system.
